The default value is false. If set to true the URL passed to the cmdlet will be URL encoded.

After calling ListDirectory, this config can be queried to determine whether or not the resource at index i is a directory (collection): webdav.ListDirectory("https://localhost/DAV/"); bool isDir = Convert.ToBoolean(webdav.Config("IsDir[0]"));

An exception will be thrown if an invalid index is specified.

When AllowHTTPCompression is True, the cmdlet adds an Accept-Encoding header to the request being sent to the server. By default, this header's value is "gzip, deflate". This configuration setting allows you to change the value of the Accept-Encoding header. Note: The cmdlet only supports gzip and deflate decompression algorithms.

This configuration setting enables HTTP compression for receiving data. When set to True (default), the cmdlet will accept compressed data. It then will uncompress the data it has received. The cmdlet will handle data compressed by both gzip and deflate compression algorithms.

When True, the cmdlet adds an Accept-Encoding header to the outgoing request. The value for this header can be controlled by the AcceptEncoding configuration setting. The default value for this header is "gzip, deflate".

The default value is True.

This configuration setting controls whether HTTP/2 connections are permitted to fall back to HTTP/1.1 when the server does not support HTTP/2. This setting is applicable only when HTTPVersion is set to "2.0".

If set to True (default), the cmdlet will automatically use HTTP/1.1 if the server does not support HTTP/2. If set to False, the cmdlet throws an exception if the server does not support HTTP/2.

The default value is True.

This configuration setting determines whether data will be appended when writing to LocalFile. When set to True, downloaded data will be appended to LocalFile. This may be used in conjunction with Range to resume a failed download. This is applicable only when LocalFile is set. The default value is False.

If the Authorization property contains a nonempty string, an Authorization HTTP request header is added to the request. This header conveys Authorization information to the server.

This property is provided so that the HTTP cmdlet can be extended with other security schemes in addition to the authorization schemes already implemented by the cmdlet.

The AuthScheme property defines the authentication scheme used. In the case of HTTP Basic Authentication (default), every time User and Password are set, they are Base64 encoded, and the result is put in the Authorization property in the form "Basic [encoded-user-password]".

This configuration setting returns the raw number of bytes from the HTTP response data, before the component processes the data, whether it is chunked or compressed. This returns the same value as the Transfer event, by BytesTransferred.

This is applicable only when UseChunkedEncoding is True. This setting specifies the chunk size in bytes to be used when posting data. The default value is 16384.

If set to True, the body of a PUT or POST request will be compressed into gzip format before sending the request. The "Content-Encoding" header is also added to the outgoing request.

The default value is False.

If set to True, the URL passed to the cmdlet will be URL encoded. The default value is False.

This option determines what happens when the server issues a redirect. Normally, the cmdlet returns an error if the server responds with an "Object Moved" message. If this property is set to 1 (always), the new URL for the object is retrieved automatically every time.

If this property is set to 2 (Same Scheme), the new URL is retrieved automatically only if the URL Scheme is the same; otherwise, the cmdlet throws an exception.

Note: Following the HTTP specification, unless this option is set to 1 (Always), automatic redirects will be performed only for GET or HEAD requests. Other methods potentially could change the conditions of the initial request and create security vulnerabilities.

Furthermore, if either the new URL server or port are different from the existing one, User and Password are also reset to empty, unless this property is set to 1 (Always), in which case the same credentials are used to connect to the new server.

A Redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the Redirect event is a good place to set properties related to the new connection (e.g., new authentication parameters).

The default value is 0 (Never). In this case, redirects are never followed, and the cmdlet throws an exception instead.

Following are the valid options:

• 0 - Never
• 1 - Always
• 2 - Same Scheme

The default value is False. If set to True, the cmdlet will perform a GET on the new location. Otherwise, it will use the same HTTP method again.

HTTP/2 servers maintain a dynamic table of headers and values seen over the course of a connection. Typically, these headers are inserted into the table through incremental indexing (also known as HPACK, defined in RFC 7541). To tell the component not to use incremental indexing for certain headers, and thus not update the dynamic table, set this configuration option to a comma-delimited list of the header names.

This property specifies the HTTP version used by the cmdlet. Possible values are as follows:

• "1.0"
• "1.1" (default)
• "2.0"
• "3.0"

When using HTTP/2 ("2.0"), additional restrictions apply. Please see the following notes for details.

HTTP/2 Notes

When using HTTP/2, a secure Secure Sockets Layer/Transport Layer Security (TLS/SSL) connection is required. Attempting to use a plaintext URL with HTTP/2 will result in an error.

If the server does not support HTTP/2, the cmdlet will automatically use HTTP/1.1 instead. This is done to provide compatibility without the need for any additional settings. To see which version was used, check NegotiatedHTTPVersion after calling a method. The AllowHTTPFallback setting controls whether this behavior is allowed (default) or disallowed.

HTTP/2 is supported on all versions of Windows. If the Windows version is an earlier version than Windows 8.1/Windows Server 2012 R2, the internal security implementation will be used. If the Windows version is Window 8.1/Windows Server 2012 R2 or later, the system security libraries will be used by default.

HTTP/3 Notes

HTTP/3 is supported only in .NET and Java.

When using HTTP/3, a secure (TLS/SSL) connection is required. Attempting to use a plaintext URL with HTTP/3 will result in an error.

If this setting contains a nonempty string, an If-Modified-Since HTTP header is added to the request. The value of this header is used to make the HTTP request conditional: if the requested documented has not been modified since the time specified in the field, a copy of the document will not be returned from the server; instead, a 304 (not modified) response will be returned by the server and the component throws an exception

The format of the date value for IfModifiedSince is detailed in the HTTP specs. For example: Sat, 29 Oct 2017 19:43:31 GMT.

If true, the component will not send the Connection: Close header. The absence of the Connection header indicates to the server that HTTP persistent connections should be used if supported. Note: Not all servers support persistent connections. If false, the connection will be closed immediately after the server response is received.

The default value for KeepAlive is false.

If the Service Principal Name on the Kerberos Domain Controller is not the same as the URL that you are authenticating to, the Service Principal Name should be set here.

This configuration setting controls the level of detail that is logged through the Log event. Possible values are as follows:

The value 1 (Info) logs basic information, including the URL, HTTP version, and status details.

The value 2 (Verbose) logs additional information about the request and response.

The value 3 (Debug) logs the headers and body for both the request and response, as well as additional debug information (if any).

When FollowRedirects is set to any value other than frNever, the cmdlet will follow redirects until this maximum number of redirect attempts are made. The default value is 20.

This configuration setting may be queried after the request is complete to indicate the HTTP version used. When HTTPVersion is set to "2.0" (if the server does not support "2.0"), then the cmdlet will fall back to using "1.1" automatically. This setting will indicate which version was used.

This configuration setting can be set to a string of headers to be appended to the HTTP request headers.

The headers must follow the format "header: value" as described in the HTTP specifications. Header lines should be separated by CRLF ("\r\n") .

Use this configuration setting with caution. If this configuration setting contains invalid headers, HTTP requests may fail.

This configuration setting is useful for extending the functionality of the cmdlet beyond what is provided.

This is similar to the Authorization configuration setting, but is used for proxy authorization. If this configuration setting contains a nonempty string, a Proxy-Authorization HTTP request header is added to the request. This header conveys proxy Authorization information to the server. If ProxyUser and ProxyPassword are specified, this value is calculated using the algorithm specified by ProxyAuthScheme.

This configuration setting is provided for use by cmdlets that do not directly expose Proxy properties.

This configuration setting returns the complete set of raw headers as sent by the client.

This configuration setting contains the result code of the last response from the server.

This setting contains the first line of the last response from the server. The format of the line will be [HTTP version] [Result Code] [Description].

This configuration setting contains the contents of the last response from the server.

If TransferredDataLimit is set to 0 (default), no limits are imposed. Otherwise, this reflects the maximum number of incoming bytes that can be stored by the cmdlet.

This configuration setting returns the complete set of raw headers as received from the server.

This configuration setting returns the full request as sent by the client. For performance reasons, the request is not normally saved. Set this configuration setting to ON before making a request to enable it. Following are examples of this request:

.NET Http http = new Http(); http.Config("TransferredRequest=on"); http.PostData = "body"; http.Post("http://someserver.com"); Console.WriteLine(http.Config("TransferredRequest")); C++ HTTP http; http.Config("TransferredRequest=on"); http.SetPostData("body", 5); http.Post("http://someserver.com"); printf("%s\r\n", http.Config("TransferredRequest"));

If UseChunkedEncoding is set to True, the cmdlet will use HTTP-chunked encoding when posting, if possible. HTTP-chunked encoding allows large files to be sent in chunks instead of all at once. If set to False, the cmdlet will not use HTTP-chunked encoding. The default value is False.

Note: Some servers (such as the ASP.NET Development Server) may not support chunked encoding.

This configuration setting specifies whether hostnames containing non-ASCII characters are encoded to internationalized domain names. When set to True, if a hostname contains non-ASCII characters, it is encoded using Punycode to an IDN (internationalized domain name).

The default value is False and the hostname will always be used exactly as specified.

This configuration specifies whether the cmdlet will attempt to use the Proxy auto-config URL when establishing a connection and ProxyAutoDetect is set to True.

When True (default), the cmdlet will check for the existence of a Proxy auto-config URL, and if found, will determine the appropriate proxy to use.

This is the value supplied in the HTTP User-Agent header. The default setting is "IPWorks HTTP Component - www.nsoftware.com".

Override the default with the name and version of your software.

When set, this configuration setting allows you to specify a different timeout value for establishing a connection. Otherwise, the cmdlet will use Timeout for establishing a connection and transmitting/receiving data.

This configuration setting is provided for use by cmdlets that do not directly expose Firewall properties.

If a FirewallHost is given, requested connections will be authenticated through the specified firewall when connecting.

If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned.

Note: This setting is provided for use by cmdlets that do not directly expose Firewall properties.

If FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the given firewall. If the authentication fails, the cmdlet throws an exception.

Note: This setting is provided for use by cmdlets that do not directly expose Firewall properties.

The FirewallPort is set automatically when FirewallType is set to a valid value.

Note: This configuration setting is provided for use by cmdlets that do not directly expose Firewall properties.

The appropriate values are as follows:

Note: This setting is provided for use by cmdlets that do not directly expose Firewall properties.

If the FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the Firewall. If the authentication fails, the cmdlet throws an exception.

Note: This setting is provided for use by cmdlets that do not directly expose Firewall properties.

When set, TCPKeepAlive will automatically be set to True. A TCP keep-alive packet will be sent after a period of inactivity as defined by KeepAliveTime. If no acknowledgment is received from the remote host, the keep-alive packet will be sent again. This configuration setting specifies the interval at which the successive keep-alive packets are sent in milliseconds. This system default if this value is not specified here is 1 second.

Note: This value is not applicable in macOS.

When set, TCPKeepAlive will automatically be set to True. By default, the operating system will determine the time a connection is idle before a Transmission Control Protocol (TCP) keep-alive packet is sent. This system default if this value is not specified here is 2 hours. In many cases, a shorter interval is more useful. Set this value to the desired interval in milliseconds.

This property controls how a connection is closed. The default is True.

In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires.

In the second scenario, if LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.

The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the cmdlet returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes).

Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.

LingerTime is the time, in seconds, the socket connection will linger. This value is 0 by default, which means it will use the default IP timeout.

The LocalHost setting contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the cmdlet initiate connections (or accept in the case of server cmdlets) only through that interface.

If the cmdlet is connected, the LocalHost setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).

This must be set before a connection is attempted. It instructs the cmdlet to bind to a specific port (or communication endpoint) in the local machine.

Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.

LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.

This; setting is useful when trying to connect to services that require a trusted port in the client side. An example is the remote shell (rsh) service in UNIX systems.

MaxLineLength is the size of an internal buffer, which holds received data while waiting for an EOL string.

If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset.

If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset.

The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.

This configuration setting can be used to throttle outbound TCP traffic. Set this to the number of bytes to be sent per second. By default, this is not set and there is no limit.

This configuration setting optionally specifies a semicolon-separated list of hostnames or IP addresses to bypass when a proxy is in use. When requests are made to hosts specified in this property, the proxy will not be used. For instance:

www.google.com;www.nsoftware.com

If set to True, the socket's keep-alive option is enabled and keep-alive packets will be sent periodically to maintain the connection. Set KeepAliveTime and KeepAliveInterval to configure the timing of the keep-alive packets.

Note: This value is not applicable in Java.

When true, the socket will send all data that is ready to send at once. When false, the socket will send smaller buffered packets of data at small intervals. This is known as the Nagle algorithm.

By default, this config is set to false.

When set to 0 (default), the cmdlet will use IPv4 exclusively. When set to 1, the cmdlet will use IPv6 exclusively. To instruct the cmdlet to prefer IPv6 addresses, but use IPv4 if IPv6 is not supported on the system, this setting should be set to 2. The default value is 0. Possible values are:

If AbsoluteTimeout is set to True, any method which does not complete within Timeout seconds will be aborted. By default, AbsoluteTimeout is False, and the timeout is an inactivity timeout.

Note: This option is not valid for UDP ports.

When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g. headers for custom authentication schemes).

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. Increasing the value of the InBufferSize setting can provide significant improvements in performance in some cases.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the cmdlet is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be sending. Increasing the value of the OutBufferSize setting can provide significant improvements in performance in some cases.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the cmdlet is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

When queried, this setting will return a string containing information about the product's build.

The default code page is Unicode UTF-8 (65001).

The following is a list of valid code page identifiers:

When queried, this setting will return a string containing information about the license this instance of a cmdlet is using. It will return the following information:

• Product: The product the license is for.
• Product Key: The key the license was generated from.
• License Source: Where the license was found (e.g., RuntimeLicense, License File).
• License Type: The type of license installed (e.g., Royalty Free, Single Server).
• Last Valid Build: The last valid build number for which the license will work.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to true to mask sensitive data. The default is true.

This setting only works on these cmdlets: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

When set to false, the cmdlet will use the system security libraries by default to perform cryptographic functions where applicable. In this case, calls to unmanaged code will be made. In certain environments, this is not desirable. To use a completely managed security implementation, set this setting to true.

Setting this configuration setting to true tells the cmdlet to use the internal implementation instead of using the system security libraries.

On Windows, this setting is set to false by default. On Linux/macOS, this setting is set to true by default.

If using the .NET Standard Library, this setting will be true on all platforms. The .NET Standard library does not support using the system security libraries.

Note: This setting is static. The value set is applicable to all cmdlets used in the application.

When this value is set, the product's system dynamic link library (DLL) is no longer required as a reference, as all unmanaged code is stored in that file.
